Gabrielle is 2*Mikhail:
G = 2M We will use this value for G next
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
G+M = 45 Now in this equation substitute for G, like this:
2M+M = 45
3M = 45 Divide both sides by 3
M = 15 This is Mikhail, and the problem says that:
G = 2(15) = 30
Gabrielle is 30 and Mikhail is 15, and 15+30 = 45 just like the problem says
